This study uses a meta-analysis to examine the functional neuroanatomy of autobiographical memory (AM), a complex process involving episodic memory, self-reflection, emotion, visual imagery, attention, executive functions, and semantic processes. The analysis includes 24 functional imaging studies and identifies a core neural network of left-lateralized regions, including the medial and ventrolateral prefrontal cortices, medial and lateral temporal cortices, retrosplenial/posterior cingulate cortices, temporoparietal junction, and cerebellum. Secondary and tertiary regions are also identified. The study examines the neural correlates of various component processes in AM, such as executive functions, self-reflection, episodic remembering, and visuospatial processing. It also analyzes the effect of variables like memory age, qualitative factors (personal significance, level of detail, and vividness), semantic and emotional content, and reference conditions on the AM network. The findings support a neural distinction between episodic and semantic memory in AM and show that emotional events shift the lateralization of the AM network.This study uses a meta-analysis to examine the functional neuroanatomy of autobiographical memory (AM), a complex process involving episodic memory, self-reflection, emotion, visual imagery, attention, executive functions, and semantic processes.
